Shouldn't be. I've done the same sort of thing with success from FreeBSD -> FreeBSD over NFS. I would think that there is probably some sort of NFS problem with the NAS. Can it also do SMB? Perhaps try mounting an SMB share and doing the same process and see if the files are valid. That would rule NFS out at least. I doubt it's your tar program, but you could try making an archive locally to rule it out for sure. -- Bill Moran Potential Technologies http://www.potentialtech.com
